What is tetralogy of fallot?

What should you know about it?

  • Tetralogy of fallot (TOF), a rare condition often refers to four collective congenital heart defects that are present at birth
  • Ventricular septal defect (VSD): A hole between the lower parts of the heart lets blood low in oxygen mix with blood that’s rich in oxygen.
  • Overriding aorta: Because of the hole between the lower parts of the heart, the aorta is positioned over both chambers instead of just one. This causes oxygen-poor blood flow out to the body for circulation.
  • Pulmonary artery stenosis: This block at the level of the right ventricular flow out tract makes it hard for blood to reach your lungs for oxygenation.
  • Ventricular hypertrophy: The muscle wall of your right lower heart chamber becomes too thick because it’s working extra hard to make up for the other heart issues.

Prenatal ultrasound

Serious heart problems are often found during an ultrasound while you're pregnant. This test shows if your baby’s heart isn’t formed properly. If anything unusual is found, a special heart scan called a fetal echocardiogram will be arranged.

Fetal echocardiogram

A fetal echocardiogram is a detailed ultrasound done by a heart doctor for children. It closely looks at your baby’s heart and the nearby blood vessels. After birth, the doctor will do another heart scan to confirm the findings.

Heart Catherization

This test checks the pressure inside the heart. It can also take pictures and help open narrow areas using a small balloon or a tiny metal tube called a stent.

Cell-Free Fetal DNA Testing

A small amount of your baby’s blood is taken to look at their genes. If the result is positive, it may mean there’s a possible issue with the DNA. Additional tests may be done before or after your baby is born, based on findings.

Karyotype

A small sample of your baby’s blood is tested to look for any problems with their genes. This test is called a karyotype if it looks at chromosomes or a microarray if it gives a more detailed view of all the genes.

treatment

How is tetralogy of Fallot treated?

Tetralogy of Fallot requires surgical treatment, typically an open heart surgery, where it repairs completely.Medicines can help manage symptoms for a while, before and after surgery.

  • Medications: Pediatric cardiothoracic surgeons may give your baby medicines to help improve blood flow, maintain normal pressure and to prevent further complications.
The tetralogy of fallot surgery involves:
  • Complete repair: A surgeon can widen the pulmonary valve and the passage to the pulmonary artery. They can also close the hole between the two lower heart chambers with a patch.
  • BT shunt procedure: Your doctor can place a small tube, called a shunt, between your child’s subclavian artery and pulmonary artery to help more blood reach the lungs.
